New Bargaining Unit

It is with great pleasure that District 13 welcomes our newest Bargaining Unit – the Professional Student Services Personnel (PSSP) of the DDSB voted overwhelmingly in June to join OSSTF. Our new members include psychologists, social workers, speech-language pathologists and interpreters to name a few. Many of our teachers will know them from the work they do in their schools and classrooms every day. Please take a moment to welcome them to our union which grows stronger every day thanks to the diversity of our members.

PSSP Executive

The first general meeting of PSSP members tool place Sept 13, 2018 at the LVIV Hall in Oshawa.  Members of the bargaining unit elected their executive team as follows:

President: Jennifer Seif
Vice-President: Andrea Malyon
Chief Negotiator-Grievance Officer: Jenifer Mascoll
Secretary-Treasurer: Laurie Light
Health & Safety Officer: Stephanie Pritchard
Educational Services Officer: Elizabeth MacDonald
Executive Officer: Amanda Frumkin
Pay Equity Officer: Laura McGill

Grid Remedy Calculation

Part of the remedy for Bill 115 involved restoring pay for members who were frozen on the grid for the 2012-2014 years.

The freeze looked like this: instead of getting your years of experience increase (horizontal on the grid) or your group rating increase (vertical on the grid) in September of 2012 and in September of 2013, you received it 98 days after the start of the school year. This would have delayed you getting your pay increase for half the year in both school years. The remedy that was settled on is seeking to pay back half the money lost due to the grid freeze.

If you were teaching at any point in time between 2012 and 2014 where you were affected by the grid freeze either in years of experience or by a group rating change, you are eligible for the grid restoration payment. Of course, this payment will depend on where you were on the grid, when you were employed by the board, if you were frozen for one year or both, if you had a rating change during that time or not. These are all very individual calculations.

The payout was included in the last pay at the end of June. It appears as a line in the Earnings box that reads OSSTFGRD.

As the District Office is closed over the summer, we have provided you with step by step instructions to check the board calculations and make sure your payout is correct. Please follow the link for these instructions which model how to calculate your restoration payment if you are in Group 1 at zero years of experience. Just follow the numbers substituting your own Group and years of experience from 2012-2014.

Grid Delay Remedy Sample Calculation

Below is the language from the Minutes of Settlement:
…an amount towards restoration to individual OSSTF/FEESO members of the impact resulting from the delay in grid movement experienced from 2012-13 to 2013-14. The amount for each individual affected member will be equivalent to half of the impact on that member resulting from the delay in grid movement.

In particular, OSSTF/FEESO endorses all of the recommendations related to improving educational opportunities for all First Nations, Métis and Inuit (FNMI) Canadians, and the need to better educate all Canadians about the history and impact of residential schools.
